Rampant stonerism is fine, assuming you don’t get so zonked that you put out records like Rolling Papers, Wiz Khalifa’s sluggish 2011 debut. The rapper apologized in an open letter to his fans, and atoned earlier this year with a slippery mixtape; now Khalifa repents in full with an album as solid as Rolling Papers was slack. Wiz’s subject matter is pretty standard: waking, baking and, between massive bong hits, babymaking with his model-fiancee Amber Rose. The beats, by Pittsburgh homeboys ID Labs and others, whip up aural smoke billows, and Khalifa’s are just off-kilter enough – “Is it ‘cuz I’m hella paid?/I think it might be/Yeah, my pocket’s hella straight” – to give you a contact high.
